Hollow in front of elbow. It contains important nerves and vessels as follows
Borders:
Base:
Imaginary
line which extends from the
medial
epicondyle
of
humerus to the
lateral
epicondyle
of
humerus. It is proximal to the apex.
Apex:
Overlapping borders of
pronator
teres
and
brachioradialis.
Medial
wall:
Lateral wall of the
pronator
teres.
Lateral wall. This is made up of the
medial wall of the
brachioradialis.
Roof: Deep fascia which covers the cubital fossa, superficial fascia and the skin together with structures which run
in the roof such as the
basilic
vein on its medial side,
cephalic
vein on
its lateral side,
medial
cutaneous
nerve
of
forearm, the
median
vein
of
forearm and the ante or
median
cubital
vein. This will also include the
terminal part of
radial
nerve as its lies on the lateral aspect of its
roof and the lateral cutaneous nerve of forearm which is a continuation of
the
musculocutneous
nerve
Floor (posterior wall): Two muscles; proximal is the brachialis; the distal is the supinator.
BONES:
Ulna,
radius,
humerus
Muscles: Supinator, pronator teres, brachioradialis, brachialis, biceps brachii
Arteries:
Brachial
artery
which
bifurcates
at the
level
of the
neck
of
radius
to

Radial
artery
whose
branches
are

Ulnar
artery

Veins:
Brachial
veins
whose
tributaries
are

Radial
vein
whose
tributary
is

Ulnar
vein

Nerves: Median nerve passes through the fossa; others include radial nerve, ulnar nerve.
